Punching machine 100 under the example 1, owing to be provided with above-mentioned warpage straightening mechanism 900, so can correct by the warpage of 900 couples of lamellar processing object W of warpage straightening mechanism.Therefore, can carry out more high-precision perforation processing.In addition, at this moment, by being blown to lamellar processing object W by each element, that can avoid taking place between the processing object W and each element when the lamellar processing object W of guiding contacts, thereby prevents the lamellar processing object W of each element damage.

And in the punching machine 100 under example 1, warpage straightening mechanism 900 is arranged on the moving-member as mentioned above.Thus, the warpage of lamellar processing object W can obtain correcting near punch position, thereby can carry out more high-precision perforation processing.

Use the perforation of 100 pairs of processing object W enforcements of punching machine of this structure, carry out as follows.And the 1st clamper 810 is controlled the processing object W that sends from conveying roller 310 in advance, and is moved to the carrying road c of punch position side under this state by the carrying road a of conveying mechanism side.In addition, be shown with reference mark (reading punch position) at processing object W subscript with indicating mark.

At first, as shown in Figure 2, by the hold of the 1st clamper 810 releasings to lamellar processing object W, lamellar processing object W is used between the metal die 730 with metal die 720 and punch die at drift, and then, use is carried out around volume around scroll wheel 410, and processing object W is in can be to the punch position condition of supplying.In this case, processing object W be in can condition of supplying after, respectively the weight of the lifting roller 510,560 of drawing mechanism 500,550 is offered the both ends of processing object W.

Then, driven in synchronism conveying mechanism 300, around volume mechanism 400 and travel mechanism 600 (the 1st travel mechanism 610) quantitatively provides processing object W by the conveying mechanism side direction around the volume mechanism side.Specifically, make conveying mechanism 300 and when volume mechanism 400 stops, under the state of releasing, lamellar processing object W is being moved by the 3rd clamper 660 by the hold of the 1st clamper 810 and 820 couples of lamellar processing object W of the 2nd clamper.

And, make lamellar processing object W to the time by the 3rd clamper 660, around lifting roller 560 decline or the rising correspondingly of volume mechanism side around volume mechanism 400 side shiftings.

Then, control splint fixation shape processing object W, simultaneously, under the state of the hold of removing 660 couples of lamellar processing object W of the 3rd clamper, bore a hole by the 1st clamper 810 and the 2nd clamper 820.

Like this, the lifting roller 510 of conveyor side and around the lifting roller 560 of volume side is that lifting is controlled in the tension force by lamellar processing object W and deadweight respectively, so can easily give lamellar processing object W with less tensile force.Consequently, can easily suppress to worsen, lamellar processing object W is implemented with more high-precision perforation processing owing to the flexible perforation precision that causes of lamellar processing object W.

Punching machine 100 under the example 1, as mentioned above, be provided with cylinder shape processing object W sent and be laminal conveying mechanism 300, with lamellar processing object W around be rolled into the cylinder shape around the volume mechanism 400, be used to strain a pair of drawing mechanism 500 that loosens at conveying mechanism 300 and the processing object W between volume mechanism 400,550, between this to drawing mechanism 500, travel mechanism 600 between 550, be provided with drift metal die 720 and the punch die punch block mechanism 700 of metal die 730 of lamellar processing object W being implemented perforation, with the clamp mechanism 800 of under the state of implementing perforation by punch block mechanism 700, controlling processing object W.Then, under punch position, vertically carry lamellar processing object W around volume mechanism 400 sides by conveying mechanism 300 side direction.

Therefore, according to the punching machine under the example 1 100, owing to be to the vertically lamellar processing object W enforcement perforation of carrying, so near the lamellar processing object W punch position can not produce warpage because of its deadweight.

Consequently, because do not need lamellar processing object W is applied with strong tensile force, thus can suppress to worsen because of the flexible perforation precision that causes of lamellar processing object W, thus can carry out more high-precision perforation processing to lamellar processing object W.

In the punching machine 100 under example 1, be provided with the moving-member of supporting punch block mechanism 700, promptly can be in the horizontal direction with vertical direction on the moving-member that moves.Thus, can easily implement perforation processing to lamellar processing object W in desirable position.

In the punching machine 100 under example 1, punch die is base portion supports by moving-member with metal die 730, and drift is that ceiling portion by moving-member supports with metal die 720.Thus, structure more complicated and bulky drift metal die are to be supported by the relatively more rich ceiling portion in space, and relatively simple for structure and punch die that volume is little uses metal die by the relatively more nervous base portion support in space.Therefore, drift can easily be realized with the design that metal die is supported on the moving-member with metal die and punch die.

In the punching machine 100 under example 1, be provided with conveying mechanism 300 sides that are provided in punch block mechanism 700, can traverse the 1st clamper 810 of controlling lamellar processing object W on the width of lamellar processing object W and be provided in punch block mechanism 700 around volume mechanism 400 sides, can on the width of lamellar processing object W, traverse the 2nd clamper 820 of controlling lamellar processing object W.Thus, because be that the lamellar processing object W that controls by the 1st clamper 810 and the 2nd clamper 820 is implemented perforation processing, can suppress effectively along carrying the warpage that direction (being horizontal direction) takes place perpendicular to lamellar processing object W.Therefore, can give lamellar processing object W and be lower than necessary stretching, suppress to worsen, can carry out more high-precision perforation processing lamellar processing object W because of the flexible perforation precision that causes of lamellar processing object W.

In the punching machine 100 under example 1, have a plurality of separate and moving-members that can move as moving-member, be provided with a plurality of separate and punch block mechanisms that can bore a hole as punch block mechanism, each moving-member is supported each punch block mechanism respectively.Thus, in mutually different field, each moving-member moves on vertical direction and horizontal direction, and can implement perforation to lamellar processing object W by the punch block mechanism of these moving-members.Therefore, can implement perforation processing at high speed.

In the punching machine 100 under example 1, drift with metal die 720 be provided with can a plurality of drifts of lifting in the lifting route in, be provided with 1 drift that selection is used for boring a hole from a plurality of drifts and make the selection mechanism of its processing of boring a hole, punch die is provided with metal die 730 and a plurality of punch dies hole of the corresponding setting of a plurality of drifts of drift usefulness metal die 720.Thus, even wear and tear at 1 drift, under the damaged situation,, needn't take off the drift metal die, just can exchange the exchanging operation of the drift that weares and teares from punching machine by of the selection mechanism of operation drift with metal die 720.Therefore, can save when the exchange drift and take off and load onto the time of drift,, improve the operating efficiency of punching machine so can shorten the exchange required activity duration of drift with metal die.

In the punching machine 100 under example 1, also be provided with the permutation roller of on the width of lamellar processing object W, the position of lamellar processing object W necessarily being controlled.Fig. 8 is the schematic diagram that the permutation roller to 1 time punching machine of example describes.

This permutation roller 260 is provided with blade of a sword portion 264 in roller body 262 both sides as shown in Figure 8.Therefore, in the punching machine 100 under the example 1, owing to can on lamellar processing object W width, correct by blade of a sword portion 264, so can carry out certain control to the lamellar processing object W position on lamellar processing object W width to the position of lamellar processing object W.Therefore, according to the punching machine under the example 1 100, can carry out more high-precision perforation processing to lamellar processing object W.

And, preferably the permutation roller is arranged on by in the space of conveying mechanism till the punching machine.Thus, can on lamellar processing object W width, carry out good control to the position of lamellar processing object W.

In the punching machine 100 under example 1, punch block mechanism 700 is punch block mechanisms of implementing perforation processing at drift with metal die 720 and punch die with the space between the metal die 730 under greater than the state of lamellar processing object W thickness.

Thus, because be that the lamellar processing object W enforcement of vertically carrying is bored a hole, so near the processing object W punch position can warpage not take place by its deadweight.Therefore, can bore a hole with the angle correct with respect to processing object, drift can successfully withdraw from from processing object.Consequently, can under greater than the situation of lamellar processing object W thickness, implement perforation processing with the space between the metal die 730 with metal die 720 and punch die at drift, so can not want stripper.Thus,, can cut down the quantity of element, reach the purpose that reduces cost and metal die is simplified the structure according to the punching machine under the example 1 100.

In addition, because processing object W bores a hole under the not subjected to pressure state, so can reduce the damage of processing object W, the trustworthiness of the aspect that improves the quality.

In addition, under greater than the situation of lamellar processing object W thickness, implement perforation processing with the space between the metal die 730 with metal die 720 and punch die at drift because be, so when perforation, needn't the lifting punch die with metal die self, lifting drift is just enough, becomes to be easy to the high speed perforation.

In the punching machine 100 under example 1, punch block mechanism 700 is to be to implement perforation under the state of 0.10mm～5.0mm with the space between the metal die 730 with metal die 720 and punch die at drift.

In the punching machine 100 under the example 1, punch block mechanism 700 is not implement perforation drift does not have the state of directing pin between with metal die 730 with metal die 720 and punch die under, thus, at drift with metal die 720 and punch die with can the large-area processing object of mounting between the metal die 730, thereby can implement perforation processing to large-area processing object.

In addition, the method for punching under the example 1 is to implement the method for perforation at the lamellar processing object W that vertically carries of punch position.

Therefore, according to the method for punching under the example 1, owing to be that the lamellar processing object W that carries on the vertical direction is implemented perforation, so warpage can not take place because of its deadweight near the processing object punch position.Consequently, needn't give lamellar processing object W,, lamellar processing object W be carried out high-precision perforation processing so can suppress to worsen owing to the flexible perforation precision that causes of lamellar processing object W with strong tensile force.

In addition, below the 2nd travel mechanism 1620, be provided with and be used to control lamellar processing object W and make it by the 3rd clamper 1660 of conveying mechanism 1300 side direction around volume mechanism 1400 side shiftings.

Punching machine 1100 under the example 2 as shown in Figure 9, conveying mechanism and around the volume mechanism the position that is provided be the situation that is different from the punching machine 100 of example 1.Promptly, punching machine 100 under the example 1 as shown in Figure 2, its conveying mechanism 300 and be arranged on plate 230 rear side around volume mechanism 400, in contrast to this, punching machine 1100 under the example 2 as shown in Figure 9, its conveying mechanism 1300 and be arranged on plate 1230 face side around volume mechanism 1400.

Therefore, according to the punching machine under the example 2 1100, because conveying mechanism 1300 and be arranged on punch block mechanism 1700 (with reference to Figure 11 (a)) face side around volume mechanism 1400, thus can easily carry out with cylinder shape processing object W be installed on the conveying roller 1310 operation or by the operations of reclaiming cylinder shape processing object W around scroll wheel 1410.

In addition, conveying mechanism 1300 can vertically move up and down shown in Figure 10 (a) and Figure 10 (b).Thus, be necessary that exchanging drift uses under the situation of metal die 1730 (with reference to Figure 11 (a)) with metal die 1720 or punch die, shown in Figure 10 (a), vertically move up and down by making conveying mechanism 1300, just can easily carry out this exchanging operation.In addition, cylinder shape processing object W is installed under the situation of the operation on the conveying roller 1310 carrying out, shown in Figure 10 (b), vertically moves up and down, just can easily carry out this installation exercise by making conveying mechanism 1300.

And, in the punching machine 1100 under example 2, though for example be the formation that conveying mechanism 1300 can vertically move up and down, but also can be around the formation that vertically moves up and down of volume mechanism 1400, can also be conveying mechanism 1300 and the formation that vertically moves up and down together around volume mechanism 1400.

Punching machine 1100 under the example 2 as shown in figure 11, drift is the situation that is different from the punching machine 100 of example 1 with metal die and punch die with the installation site of metal die.In addition, be accompanied by drift with metal die and punch die with metal die the different of position are set, the structure of moving-member also changes.That is, the punching machine 100 under example 1, as shown in Figure 5, punch die is on the base portion (workbench 623) that is supported on moving-member 631 with metal die 730, drift is to be supported on by in the ceiling portion 635 of moving-member 631 with metal die 720.In contrast to this, the punching machine 1100 under the example 2, shown in Figure 11 (a), drift is supported on metal die 1720 on the base portion 1623 of moving-member 1631, and punch die is supported in the ceiling portion 1635 of moving-member 1631 with metal die 1730.

Therefore, according to the punching machine under the example 2 1100, structure more complicated, the drift that weight is big are supported on the base portion 1623 with metal die 1720, and punch die relatively simple for structure, that weight is little is supported on ceiling portion 1635 with metal die 1730.Consequently, because the weight balancing of moving-member is optimized, moving-member obtains lightweight, thus can make the mobile high speed of punch block mechanism, and then the processing of boring a hole at high speed.

In addition, drive the driving mechanism that drift uses and be supported on the base portion 1623 with metal die 1720 because comprise, so can make the mobile vibration class that is accompanied by the perforation generation become minimum with parts 1631 at interior drift.Therefore, can carry out more high-precision perforation processing to lamellar processing object W.

In addition, because can add the mechanism of the drift break flour that produces man-hour, be arranged on relatively more rich ceiling portion 1635 places, space, so the processing of drift break flour is become easy with handling to bore a hole.

So, punching machine 1100 under the example 2, though its conveying mechanism and position and drift are set with metal die and punch die the situation that the position is different from the punching machine 100 of example 1 that is provided with metal die around volume mechanism, but identical with the punching machine 100 of example 1 is vertically to be carried around volume mechanism 1400 sides by conveying mechanism 1300 side direction at punch position upper thin sheet shape processing object W.

Therefore, according to the punching machine under the example 2 1100, because can bore a hole processing to the lamellar processing object W along the vertical direction carrying, near the lamellar processing object W the punch position of place can be owing to warpage takes place in its deadweight.

Consequently, because needn't give lamellar processing object W,, lamellar processing object W is carried out more high-precision perforation processing so can suppress to worsen owing to the flexible perforation precision that causes of lamellar processing object W with strong tensile force.

2 times punching machines 1100 of example also are provided with: the lifting roller 1510 of tension force by lamellar processing object W and deadweight control lifting, control lamellar processing object W and make it by 3rd clamper 1660 of conveying mechanism 1300 side direction around volume mechanism 1400 side shiftings.Under the state of removing lamellar processing object W hold by the 1st clamper 1810 and the 2nd clamper 1820, by the 3rd clamper 1660 lamellar processing object W to around volume mechanism 1400 side shiftings, then, when controlling lamellar processing object W, remove the state of the hold of 1660 couples of lamellar processing object W of the 3rd clamper and implement perforation down by the 1st clamper 1810 and the 2nd clamper 1820.

Therefore, according to the punching machine under the example 2 1100, the lifting roller 1510 of drawing mechanism 1500 consequently can give lamellar processing object W with more weak tensile force by tension force and the deadweight control lifting of lamellar processing object W.Consequently, just can easily suppress to worsen, lamellar processing object W is implemented more high-precision perforation processing owing to the flexible perforation precision that causes of lamellar processing object W.

In this case, as the punching machine 100 of example 1, because be not to apply with tensile force, so can make the tensile force that gives lamellar processing object W littler by lifting roller around the volume side.Therefore, can suppress to worsen, lamellar processing object W is implemented high accuracy perforation processing more owing to the flexible perforation precision that causes of lamellar processing object W.

And, in the punching machine 1100 under example 2, make lamellar processing object W to the time by the 3rd clamper 1660 around volume mechanism 1400 side shiftings, conveying mechanism 1300 stops.In addition, corresponding make lamellar processing object W to the time by the 3rd clamper 1660 around volume mechanism 1400 side shiftings, suitably drive around volume mechanism 1400.

In 2 times punching machines 1100 of example, and then be provided with the position that is determined at the lamellar processing object W on the lamellar processing object W width, and can dynamically be controlled at the controlling organization (not shown) of the lamellar processing object W position on the lamellar processing object W width according to this measurement result.Thus, can control the position of the lamellar processing object W on lamellar processing object W width accurately, lamellar processing object W is carried out more high-precision perforation processing.
